An expert from Graceland says the photos were likely taken while Elvis was in Florida filming the 1962 movie Follow that Dream. The movie featured scenes from Crystal River, Tampa and Ocala and the selection of snapshots also included one of two twin boys -- believed to be Gavin and Robin Koon --who were also in the film.

There is a bit of mystery surrounding the photos. They originally came from a house demolished in Thonotosassa about three years ago, and the man who owned the property has since passed away. He was also a collector, so we may never know who took the photographs.

But one thing is clear: just like these old black and whites, the mystique of Elvis never seems to fade away.

Auctioneer John Harris says, "I just know when I've shown these pictures to friends, the look on their faces ranges from shock to disbelief, and some of the older ladies need oxygen."
